Stuck on GRUB screen Ubuntu 12.04

Stuck on GRUB screen Ubuntu 12.04

I installed ubuntu 12.04 alongside with windows 8. After installing i
restarted computer and I found my self stuck on GRUB screen(I dont know
what to call that). So I press power button and restarted my computer and
it booted windows 8 without any OS selection menu.
So in order to get Ubuntu in OS selection menu I used EasyBCD, and added
Linux OS in menu with GRUB2 selected in kernel selection. Now again from
OS selection menu when I choose Ubuntu I find myself on GRUB4DOS screen.
Can somebody help me please?
PS: On my system windows 8 was not preloaded I have installed it.
This is the GRUB screen on which I am stuck after trying to boot in the
ubuntu.
